You are right about domains like ".beauty" but also don't forget that scammers also like to use character substitution and similarity in the pronunciation of the keyword. Usually, when a new player appears in a niche, scammers quickly react and purchase similar domains, so in this case one of the effective methods is preventive action (that is, the mixer owners should be the first to buy as many similar domain names).
Despite that, there is no guarantee that there will be no phishing and fake sites. Scammers can be very creative, with such a large number of custom domain extensions, they almost have an unlimited number of possibilities.
After a short check, I found several similar domains by "mlxy" term, it is not possible to cover all options.
